# The actual value of the acceleration of gravity is $9.8\ m/s$. Physics students in a laboratory experiment use a pendulum to determine the acceleration of gravity. Their experimental value is $9.2 m/s$.What is their percent error?

$6.1$%

##### SOLUTION
Absolute error in $g$:  $\Delta g = |9.8 - 9.2| =0.6$  $m/s$
$\therefore$ Percentage error $= \dfrac{\Delta g}{g_{actual}} \times 100 = \dfrac{0.6}{9.8} \times 100 = 6.1$ %
